This invention relates to a slicing machine of the hand-operated rotary cutter type adapted to be clamped to a table or other available support for use in slicing potatoes,

5 beets, cabbage, lettuce and otller vegetables and involves an automatically operated follower for feeding the work to the rotary cutter.

The main object is to provide a simple and l highly efficient device of this character which may be manufactured and sold at a comparatively low cost and used in households for the various kinds of work to whicll it is adapted. f 15 One of the specific objects is to provide the device with a relatively broad work-supporting shelf having a guide flange at one side along which the work may be fed tothe cutter.

Another object is to provide the automatic feeding means for the follower with a'sectional nut capable of being released for quick return of said follower at the end of the slicingl operations.

Other objects and llses relating to specific parts of the apparatus will be brought out in the following description.

In the drawings 1 Figure l is a top plan of a slicing machine 30 embodying various features of my i inven-v tion. Figures 2 and' are sectional views taken on lines 2 2, and 3 3,V respectively, Figure l.

Figure 4 is a detail sectional view through the cutter head showing the manner ofv fastening the cutter blades in operative position.

Figure is a side elevation partly Ain section of a modified means for feeding the follower and work to the cuttersl' As illustrated, this machine comprisesa bracket clamp 1 having its lower vend provided with a horizontal slot 2 for receiving a portion of a table or other'support -5 Q shown by dotted lines in Figure 2, the upper wall as 3 of the slot being adapted to rest upon the upper surface of the support czwhile the lower wall or arm 4C- of the slot is provided with a threaded aperture 5 for receiving a thumb screw 6 5 192e.` serial No. 102,384.

the latter being provided with aV flat head 7 for engaging the underside of the table wand holding the machine in operative position on said support.

The bracket 1 lis provided witharms 8 and Q projecting upwardly froml the upper wall 3 of the slot 2 for receiving and supporting at their upper ends a horizontal work table l0 which extends forwardly some distance beyond the arm @it 9 and is provided near its opposite ends with depending journal'bearings l1 and l2 for receiving the opposite ends of a rotary screw shaft l3 The majorV portion of the shaft l3 between the bearings l1 and l2 is threaded at M and is Vadapted to be engaged by a sectional nut which is pivoted at 16 vto a sliding carriage l7 and is provided with a finger piece 18 'by which it may be disengaged from the threaded portion y lt of theA shaft to allow the carriage l7 to be returned by hand independently of the shaft, butis yieldingly p held in engagement with the shaft by a coiled spring 18 Y The carriage 17 is; movable length wise of the shaft 13 in a lengthwise slot 19 in the work table 10 and is pro; vided with a follower 20 extending above the upper face of thetable 10 and provided on its front face with a series of spurs 21- for engaging the work and holding it against lateral slipping lnove-` m ment, said follower being also provided with a rearwardly projeeting'handle 22 by which the carriage supporting thesalne may be moved along the work table.

The rear end of the shaftw 13 is pro# N vided with a hand crank 23 by which it *i may be rotated.V

A circular cutter supporting disk 24 is secured to the front end of the shaft 13 and isprovided with a series ofl in this instance four` tangential slots 25 arranged in uniformly spaced relation about the axis of the shaft 13 substantially tangential to the periphery thereof for receiving a corresponding number of knife blades 26 1 Q These knife blades are secured by bolts "L -27- to the outer faces of axially inclined ribs or bosses -28- on the front face of the disk #Q4- to support the knives -264 in planes at an angle to the plane of rotation 0f the disl e241- with their inner cutting edges extending through their correspond-- of the shaft -18-, the maj or portion of the,

distance between said shaft and the periphery of the disk -24- so that the knives may be used to cut vegetables of relatively large diameter.

The object in extending the knives -24-- tangential to the periphery ofl the shaft 13- is to cause them to cut the articles operated upon with a shearing motion.

The work-table -l0 extends laterally some distance beyond opposite sides of the shaft 13- with its upper surface in a horizontal plane above said shaft, for supporting relatively large articles and is provided along its rear longitudinal edge with an upwardly and inwardly projecting guide flange -30- against which the work is adapted to rest and to guide said work in its forward movement along the table toward the cutter.

A guard plate -31- is secured at one end to the flanged side of the table -10 and extends across the periphery and front face of the cutter disk -24- in spaced relation to said disk for concentrating and deiiecting the sliced material downwardly into an underlying receptacle, not shown.

Operation When it is desired to use this device for cutting potatoes and other vegetables it may be clamped to a table or equivalent support -ain the mannerdescribed ready for use.

The carriage -17 and with'the follower -20- thereon' are withdrawn from the cutter -24- a sufficient distance to permit the work to be sliced to be placed upon the table `-V-10 between the cutter disk and follower with one side of the work resting against the guide flange -30-. i

The shaft -13- may then be rotated by means of the hand crank -23- to cause the follower to feed the work forwardly against the inner face of the cutter 24-wvhile at the same time the cutter is being rotated by the shaft -13- to successfully move the cutting blades -26- into cutting engagement with the work for slicing the same and allowing the slices to pass through the slots -25-.

The cutting edges of the blades -Qfface in the direction of rotation of the disk -24- and cooperate with the front edge of the guide flange -30- to cut the vegetables or other articles into slices as the disk continues to rotate, the iiange -30- serving by the cutters.

As the cutter disk is rotated more or less rapidly the slices will be thrown rearwardly from the frontface of the cutter with more or less force against the deiiector plate -81 which serves to deflect the slices downwardly where they may be collected at the underside of the cutter in any suitable receptacle, not shown.

l/Vhen the slicing operation is completed the carriage may be returned by hand by simply releasing the nut section -15- from engagement with the threadedshaft -13-.

in Figure 5 is shown a modified means for Y feeding the carriage YZ-toward the cutter consisting of a coiled spring -l4 interposed between the bearing -l1- and vcarriage l7- thereby avoiding the'use of the threaded portion -14 and nut -15-..

In the use of this modification the follower -20- is drawn back by hand against the action of the spring -14- and the ar-v ticle to be sliced is then placed between the follower and cutter which latter is rotated to hold the work against lateral displacement in the manner described, the spring -14- v serving to feed the follower -20- and work engaged thereby forwardly toward the cutter as the slicing operation continues.

The entire frame 1-,l follower -20- and cutterl disk 24- are `preferably made of cast iron cut away as much as possible without sacrificing its strength to reduce its weight and cost of manufacture, the arm -9-- being preferably Y-shaped so that its opposite arms may support the worktable -lO- at opposite sides of the shaft -13- as shown in Figure 3. Y

What I claim is: l

A slicing machine of thel characterV described comprising a work table having aV central lengthwise opening therethrough'and journal bearings at opposite ends of the openings,a screw shaft extending lengthwise of the opening beneath the'work" table and in vertical alignment with said opening, said shaft having its opposite ends cylindrical vand journaled in said bearings and its intermediate portion provided with screw threads, a hand-crank on' one end of-tlie shaft, a

clamping device depending from the end of Y the work table nearest the hand-crank for clamping the machine toa support, afrotary disk on the other end of the shaft provided with cutters arranged in uniformly spaced relation circumferentially and tangential tov Y the shaft, al follower movable lengthwise of and within the opening in the work table and in screw engagement with the threaded por-V tion of the shaft to be actuated thereby as the shaft is rotated, a guide flange secured to and projecting upwardly from one of the longitudinal edges of the work table some dis- '5' tance from the opening, and a guard plate secured to the same side of the work table as the flange and projecting around the edge and across the outer face of the disk in the plane of the upper surface of the work table to serve the double purpose of guarding the cutters and also for delecting the severed materials downwardly from the cutters.

In witness whereof I have hereunto set my hand this 3d day of April, 1926.
